This patch touches many files but changes absolutely no functionality.
The goal here is to make future merges with worldedit produce fewer
conflicts that have to be resolved.
This patch was made by painstakingly diff'ing files and copying changes
over from the last upstream merge commit (02c6f11b) into this codebase.
